Re: Facebook is paid for by advertisers.
However, if someone is bothering to advertise to you it means you have discretion as to whether to buy their product, so you also have discretion as to whether you fund Facebook indirectly.
Advertising is a necessary evil. Whether you are making supercars, solar panels or even low cost water treatment for poor countries, if nobody knows about the product it is going nowhere. And if things are produced in low volume, they cost more to make.
I've just located (and bought) an essential part for a vintage restoration project in Greece. Without advertising I'd be stuck.
The quality of advertising, now, different matter.
